Explanation:
The answer is pretty simple. The question is asking about 10m/s and 20m/s right? Take a look at the energy at each point on the graph. At 10m/s the kinetic energy is 100 on the graph. At 20m/s the kinetic energy is 400. You'll notice that 100 x 4 is 400 - That's the answer.
You can also prove this mathematically. The formula for kinetic energy is

The question says: constant mass so we can ignore that for now.
(1/2) * 10^2 is (1/2) * 100 = 50
for the 20m/s ball it would be
(1/2) * 20^2 = 400 * 1/2 = 200
Once again, you see that it is 4x
HTML5
HTML5 has fewer plug-ins like the ability to standardize how audio and video are presented on a Web page. It introduces the <video> element designed to remove the need to install 3rd party add-ons and plug-ins like adobe flash player. It also adds the <audio> element too that allows pages to smoothly add audio files.

Explanation:
Named ranges are a very important tool in Microsoft Excel. It is used in assigning a name to a particular number of cells. It is great for automation and makes formula much easy to understand and use.
One way to create named ranges is theory the Name Box.
To create named ranges in the design marketing sheet we do this;
1) We click on cell B8 and then navigate to the name box at the top right corner of the sheet just above the column A.
•The name box is where the cell address of any cell that is active is displayed.
•You would see that “B8” is displayed on the name box.
• Double click on the name box and type in the appropriate name, in this case - Design_Fee.
• Press enter and you have your named range.
You do the same for the other named ranges.
Note that: Named ranges must contain letters, numbers or underscore.
That means that the production vause a loss in supply and demand
